"The URL shortening service tr.im is shutting down after discovering that nobody wants to buy it. The latter fact may not be surprising to many readers. But it did to the tr.im people, whose web page announces that tr.im is now in the process of discontinuing service, effective immediately. Statistics can no longer be considered reliable, or reliably available going forward. However, all tr.im links will continue to redirect, and will do so until at least December 31, 2009. Your tweets with tr.im URLs in them will not be affected. No business we approached wanted to purchase tr.im for even a minor amount. There is no way for us to monetize URL shortening -- users won't pay for it -- and we just can't justify further development since Twitter has all but annointed bit.ly the market winner. There is simply no point for us to continue operating tr.im, and pay for its upkeep." - Dan Smith

I saw where they were back up. Personally tr.im worked about 60% for me so I won't miss or use them anyway. I did like the sour grapes comments on their home page about Twitter and bit.ly haha - cheapsuits
